Colour Camera sample application.
---------------------------------

Files:
    ccmsmpl1.c      Code.
    errmsg.c        Error message handling.
    ccmsmpl1.mak    To make the executable.
    ccmsmpl1.ini    To control program.

This samples shows how to load a CPF file and grab an image from a colour
camera.  It also shows how to display the image, accounting for possible
data convertion in order to display the data.  The images are grabbed and
displayed continuously until the user exits the program.

================================================================================

Running the program:
    The program as no command line parameters but it has some useful keys to
    use while running.

    Q or q  to quit the program.
    R or r  to display the red component of the image.
    G or g  to display the green component of the image.
    B or b  to display the blue component of the image.
    C or c  to convert the image to fit the display mode.  This is done
            automatically if no key is pressed.
    I or i  to bypass the data convertion and display the image as is acquired.
            This may not always look right if there are some acquire mode and
            display mode differences, or the display mode is not supported by
            Vesa or the hardware.

================================================================================
Data convertion is required when the mode for displaying the data does not
match the mode of data is being acquired.   For example, grabbing data in
5:6:5 mode but displaying it in 5:5:5 mode.  To do this the following needs to
be done to the .ini file (all other lines are commented out):

Section         Parameter to use.
[Init]          XPGOutFile = xpg.out

[Display]       Palette = ..\..\..\pal\palette.0
                VGATextMode = 0x100
                VGADirectColourMode = 0x113

[Camera]        CPF =..\..\..\cpf\RGB565.cpf

[ColourImage]   NumPixelsForDisplay = 640
                NumLinesForDisplay  = 480
                OutDataFormat = P_16_BIT_PACKED_555

This will cause the grabbed image to be separated into it's RGB components
and recombined into the selected ouput format.

Similarly if the VGA does not support true X:8:8:8 mode and the camera grabs
in that mode then the .ini file is set to:

Section         Parameter to use.
[Init]          XPGOutFile = xpg.out

[Display]       Palette = ..\..\..\pal\palette.0
                VGATextMode = 0x100
                VGADirectColourMode = 0x115

[Camera]        CPF =..\..\..\cpf\RGB32.cpf

[ColourImage]   NumPixelsForDisplay = 640
                NumLinesForDisplay  = 480
                OutDataFormat = P_24_BIT_PACKED_888
